A tramp lie down and sleep in the park. He had been sleeping for about 5 minutes when a couple walked by. The man stopped, woke the tramp up , and asked him, "Excuse me.

Do you know what the time is?" The tramp replied, "I'm sorry - I don't have a watch, so I don't know the time."

The man apologised for waking the tramp and the couple walked away.

The tramp lay down again, and after a few minutes went back to sleep. Just then, a woman, who was out walking her dog, shook the tramp's shoulder until he woke up again.

The woman said, "I'm sorry to trouble you, but I'm afraid I've lost my watch - do you happen to know the time?" The tramp was a little annoyed at being woken up again, but he politely told the woman that he didn't have a watch and didn't know the time.

After the woman had gone, the tramp had an idea.

He opened the bag that contained all his possessions and got out a pen, a piece of paper and some string. On the paper, he wrote down, 'I do not have a watch. I do not know the time'.

He then hung the paper round his neck and eventually dropped off again.

After about 15 minutes, a policeman who was walking through the park noticed the tramp asleep on the bench, and the sign around his neck.

As a crowded airliner is about to take off, the peace is shattered by a 5-year-old boy who picks that moment to throw a wild temper tantrum. No matter what his frustrated, embarrassed mother does to try to calm him down, the boy continues to scream furiously and kick the seats around him.

Suddenly, from the rear of the plane, an elderly man in the uniform of an Air Force General is seen slowly walking forward up the aisle. Stopping the flustered mother with an upraised hand, the white-haired, courtly, soft-spoken General leans down and, motioning toward his chest, whispers something into the boy's ear.

Instantly, the boy calms down, gently takes his mother's hand, and quietly fastens his seat belt. All the other passengers burst into spontaneous applause.

As the General slowly makes his way back to his seat, one of the cabin attendants touches his sleeve.

"Excuse me, General," she asks quietly, "but could I ask you what magic words you used on that little boy?"

The old man smiles serenely and gently confides, "I showed him my pilot's wings, service stars, and battle ribbons, and explained that they entitle me to throw one passenger out the plane door on any flight I choose." Selengkapnya/Read more>>
